MRF392

Overview

The MRF392 is a dual RF power transistor designed for wideband large-signal output and driver amplifier stages operating between 30 MHz and 500 MHz. It integrates two transistors in a single package with separate base and collector leads and common emitters, facilitating push-pull configurations. Specified at 28 V and 400 MHz, the device delivers an output power of 125 W with typical gain of 10 dB and efficiency of 55%. Built-in input impedance matching networks support broadband operation, while gold metallization ensures high reliability.

Feature Summary

• Integrated input impedance matching networks enable broadband performance across the specified frequency range.
• Push-pull configuration reduces even-numbered harmonics for cleaner signal output.
• Dual-transistor architecture within a single package provides space-saving design with separate base and collector leads.

Applications

• Wideband large-signal output amplifier stages
• Driver amplifier stages in RF systems
• Broadband applications requiring harmonic suppression

Procurement Notes

Verify component authenticity through authorized MACOM distributors or official channels. Confirm datasheet revision status (Rev. V1) matches design requirements. Ensure handling procedures align with ESD protection standards for RF power devices. Validate thermal management solutions for continuous operation at rated power levels.

Selection Notes
